FLAXSEED-CLEANER.

SPECIFICATION forming part of Letters Patent No. 324,275, dated August 11, 1885.

Application filed March 19, 1885.

To all whom it may concern;

Be it known that I, THOMAS R. Rosina, a citizen of the United States, residing at San J os, in the county of Santa Clara and State of California, have invented new and useful Improvements in FlaXseed-Gleaners, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to an improvement in flaXseed-cleaners; and it consists in the pe culiar construction and combinations of devices that will be'morc fully set forth herein` after, and particularly pointed out in the claims. A

In the accompanying drawings, Figure 1 is a side elevation -of a machine embodying my invention. sectional view of the same.

4Arepresents a rectangular frame,in one end of which, near its upper side, is journaled a transverse shaft, B, to which is secured a blower, C, that works in a case, D. To one end of this shaft is secured a spurred pinion, E, which meshes witha spurred wheel, F, and a larger. driving-wheel, G, which wheels are journaled on projecting spindles that are secured to the frame.

H represents a shoe, the sides of which are in openings that are made inthe sides of the frame. The shoe is suspendedin theframe by rods I, and is connected to the pinion E by a rod, h. Vhen the shaft B is rotated, the shoe is reciprocated. In the upper inner end of the shoe is placed an inclined feed-board, K, which is beneath the opening inthe bottom of the hopper L, that is securedto the vupper side of the frame, and in the shoe, above the lower side of the board K, is journaled a bar, M, having projecting teeth m, which extend into the hopper, stirring the ilaxseed therein, and thus facilitating its passage onto the inclined feed-board K. In the shoe is located an inclined sieve, N, the upper end of which communicates with the board K,and the lower end of which projects out beyond the shoe, as shown. This sieve can be secured at any desired angle in the shoe by means of the bolts n and the series of openings n', that are made in the sides of the shoe. Vert-ical openings h are made in the sides of the shoe, near the lower end thereof.

. Q represents a rack that is composed of 1on- Fig. 2 is a vertical longitudinal.

(No model.)

gitudinu-l slats o and transverse cross-bars o. This rack bears against the under side of the sieve N, being supported by a cross-beam, P, the ends of which project out through the openings li in the shoe and slide upon vertical rods R, which are secured in blocks r, that are bolted to the sides ofthe frame. Coiled springs S are placed on the rods It and bear against the underside of the beam P, and thus keep' the rack O inxcontact with the under side of the sieve N. The lower ends of the springs are supported in stirrups S', that are suspended by chains Sl from hooks S3, that are secured to the upper blocks, r. The tension of the springs on the ends of the beam I? may be regulated'by detaching the chains from the hooks and securing them thereto by different links.

T represents a rack that is similar in construction to the rack O, and that bears against the upper side of the sieve N.' This rack is secured by chains t to the sides of the frame. By this construction it will be understood that while the sieve N reciprocates,the racks which bear against it remain practicallyimmovable. The function of the upper rack is to force the flax through the sieve and preventit from accumulating in bunches and sliding down and off the sieve, and to force the large seeds and foreign substances rapidly down and off the sieve. The lower rack is for the purpose of keeping the sieve from clogging.

Beneath the sieve N, and secured in the vi` brating shoe, is an inclined grain-board, U, the lower end of which projects slightly beyond the outer side of theshoe, as shown.

V represents a frame that is hinged in the i In guideways o', formed in the inner sides of the frame V, is secured a reciprocating screen, X, the meshes of which are finer than those of thesieve N. To the outer upper end of the screen X `is secured a board, X', which projects beyond the frame A a suitable distance below the sieve N. A rock-shaft, Y, is journaled in the frame A, and has an arm, y, that is connected to the screen X by a connecting-rod, 1 One end of the rock-shaft has a crank-arm, i2, that is connected to the gearwheel F by a pitman, y". An inclined board, Z, is secured in the frame A above the frame V. To the lower side of this board is secured a piece of canvas, A', which bears upon the upper side of the screen X. The lower end of the canvas is secured to a bar, A2, that is suspended beneath a crossbar, c, of the frame V.

B is a rectangular frame that is arranged under the screen X: rlhis frame is supported by flat springs B2, that are secured to it and to a cross-beam, o1', ofthe frameV. In the frame B are journaled a series of rollers, B, that bear against the under side of the screen X.

As the screen reciproeates it is cleaned by the rollers. The function of the canvas A is to prevent small seeds from rolling or bounding ofl the screen and to force them through the screen, while the flax passes between the screen and the canvas and is delivered at the lower end of the screen.

Vhen the machine is in operation, the fan or blower forces a current of air through the frame or easingA inthe direction indicated by the arrows in Fig. 2, and winnows the flax as it falls from the grainboard onto the screen X.

Having thus described my invention, I clai 1n l. The combination of the frame or casing, the reciprocating shoe, the sieve located in the shoe and adjustable therein, the cleaning-rack arranged under the sieve, the supporting-beam P therefor, passing through openings in the sides of the shoe, vertical rods R, passing through the ends of the beam P, springs on the rods tosupport the beam P,stirrups S, suspending-chains S2 and hooks S3, and means for supporting the hooks, the lower ends of the springs bearing on the stirrups, substantially as described.

2. The combination of the frame or easing, the reciprocating shoe, the sieve located in the shoe and adj nstable therein, the stationary cleaning-rack arranged under the sieve, a supporting cross beam therefor passing through openings in the sides of the shoe, vertical rods secured to the casing and passing through the ends of the eross-beain, springs on the rods to support the rack, and means for regulating the tension of the springs, substantially as described.

In testimony that I claim the foregoing as l my own I have hereto aixed lny signature in presence of two witnesses.
